Put the finely chopped prawns into a bowl, then add the ginger, garlic, soy sauce, and egg white. Stir well to combine the ingredients.
Spoon a quarter of the prawn mixture onto each slice of bread. Spread to ensure you get all the mixture to the edge of each slice.
Put the sesame seeds onto a plate, take one of the slices of bread and place it prawn mixture side facing down so that the sesame seeds will stick to it. Repeat with the three other slices.
Preheat the air fryer for 7 minutes at 200C. Using a knife, carefully slice the pieces of bread into four triangles.
Carefully place the triangles into the air fryer. Make sure they're well-spaced apart - you may need to cook the toasts in 2 batches.
Brush or spray vegetable oil over the top each prawn toast, then air fry at 190C for 8 minutes. Check after 5 minutes to ensure the toasts aren’t burning. Depending on your model of air fryer, it's worth keeping an eye on it. If you like them crispy, 8 minutes should be fine!
Serve either on their own or with a dipping sauce of your choice, and garnish with sliced spring onions.
Notes
Optional variations:
Spicy version - add chilli paste, sriracha or chopped fresh red chilli to the prawn mixture.
Extra aromatics - add finely sliced spring onions, chopped coriander or lime zest to the prawn mixture.
Bread swaps - try brioche for richness, thin cut sourdough or gluten-free bread.
